  • Process for laser scribing a pattern in a planar laminate
    Patent number: 5702565
    Abstract: An improved dielectric layer of an electroluminescent laminate, and method of preparation are provided. The dielectric layer is formed as a thick layer from a ceramic material to provide:a dielectric strength greater than about 1.0.times.10.sup.6 V/m;a dielectric constant such that the ratio of the dielectric constant of the dielectric material to that of the phosphor layer is greater than about 50:1;a thickness such that the ratio of the thickness of the dielectric layer to that of the phosphor layer is in the range of about 20:1 to 500:1; anda surface adjacent the phosphor layer which is compatible with the phosphor layer and sufficiently smooth that the phosphor layer illuminates generally uniformly at a given excitation voltage.The invention also provides for electrical connection of an electroluminescent laminate to voltage driving circuity with through hole technology. The invention also extends to laser scribing the transparent conductor lines of an electroluminescent laminate.
    Type: Grant
    Filed: May 23, 1995
    Date of Patent: December 30, 1997
    Assignee: Westaim Technologies, Inc.
    Inventors: Xingwei Wu, James Alexander Robert Stiles, Ken Kok Foo, Phillip Bailey

  • Door edge and hinge guard
    Patent number: 4344253
    Abstract: A door edge and hinge guard in the form of a U-shaped member is secured to a door frame longitudinally thereof to protect the edge of an open door and its hinge therein by resiliently deflecting objects such as shopping carts and the like away from contact with the edge of the door and the hinge.
